LOOM FOR WE AVING HAIR CLOTH.

SPECIFICATION forming part of Letters Patent No. 308,489, dated November25, 1884.

Application filed October 9, 1883. (N model.)

To all whom it may concern.-

Be it known that we, ROBERT C. GREEN- HALGH and JACKSON WAnswoRTH,citizens of the United States, and residents of Philadelphia,Pennsylvania, have invented certain Improvements in Looms for WeavingHair Cloth, of which the following is a specification.

Our invention .consists of certain improvements in positive-motion loomssuch as are used for weaving hair cloth, the improve ments comprisingcertain details in the construction of the loom, with the object ofrendering it more efficient in action than looms of this class asheretofore constructed.

In the accompanying drawings, Figure 1, Sheet 1, is a side view of ahair-cloth loom of the character to which our invention relates; Fig. 2,Sheet'2, a transverse section of the loom back of the breast-beam, thehair-troughs and selecting devices being omitted; Fig. 3,

a perspective view of the devices for controlling the heddle-operatingmechanism; Fig. 7,

a sectional view of said mechanism on a larger scale; and Fig. 8, Sheet6, is aview similar to Fig. 6, but showing some modifications.

In Figs. 1 and 2, A A represent the opposite side frames of the loom,having suitable bearings for the studs of the lay B, for the shafts Dand D, and for the spindles of the warp-beam E, cloth-beam E, and thevarious guide-rollers common to looms of this class. 40 The shafts D Dare connected by spur-gearing, as shown by dotted lines in Fig. 1, andthe said shaft D has a crank, a, connected by a rod, a, to a toothedsegment, a hung to a pin on the frame, and gearing into aspurpinion, (1.on the shaft of a drum, a, round which and round guide-pulleys a on thelay B passes a cord, a the opposite ends of which are connected to aslide, F, adapted to a dovetailed guide, 6, on the front of the lay, and

serving as ashuttle-earrier, as described hereinafter, this slide beingcaused to traverse from end to end of the lay as a movement of rotationor partial rotation first in one direc tion and then in they other isimparted to the drum to by the mechanism described. The 5 5 shaft D hasa drum, d, which is connected by a chain belt, (1, with a drum, d", theshaft of which is carried by a bracket, A on the frame A, and has a cam,d, a crank-pin on which is connected by a rod, (2, to a slide, (1 guidedin the bracket, and having at the lower end a fixed finger, d, and apivoted finger, (1 the latter being actuated by the cam (1 through themedium of a lever, (1 so that the fingers, when open, are caused todescend into the hair-trough d, and then to close, so as to nip a hairwhich is elevated by the rise of the fingers into the path of thenipping-jaws of the shuttle.- The hair-trough is traversed beneath thefingers by a rod, d connected to a crank-pin on a ratchet-wheel, d, thelatter being actuated by a lever, (1, connected by a rod, (1 to the rod(2* of the slide (1 The hairtrough and thehair-selecting devices, itshould be understood, are repeated at the opposite 7 side of the loom.An eccentric, f, on the shaft D is connected by a rod,-f to an arm, f,on a rock-shaft, f adapted to bearings in a frame at the top of theloom, said shaft having other arms, f connected by rods f to bars f, oneof which acts directly upon shoulders on rods f and the other uponhooked fingers f, pivoted to said rods. The rods f are connected bybell-crank levers f and cords f 9 to the heddle-frames G, the properselection of the rods 8 5.

being governed bya pattern-drum, f and levers f, and thepattern-drumhaving aratchet-Wheel,f, acted on by a pawl, f, hung to oneof the barsf. (See Fig. 7.) All of these parts are common to the presentlooms of 0 the class to which our invention relates, and we have shownand described them simply to give an idea of the construction andoperation of the loom, having done which we will now proceed to describethe parts to 5 which our invention relates. The slide F, which is guidedon the front of the bar 9 of the lay, overlaps said bar and in thisoverlapping portion of the slide are formed bearings for two shafts, hh, each of which has at its outer end a grooved pulley, i, and at theinner end a roller, m, portions of the said rollers projecting above thetop of the plate, as shown in Figs. 3 and 4. The shuttle J has a centralroller, n, projecting beneath the same, and having a bearing upon therollers m, the opposite ends of the shuttle projecting over bearings 2 pon the slide F, and said shuttle being held close to or against the reedby an overhanging bar, K, which forms part of the lay, the warp-threadslying between the rollers m and a and between the bottom plate of theshuttle and the bearings p 19.

To suitable lugs at the opposite ends of the bar 9 of the lay aresecured the opposite ends of a cord, I, which passes around the pulleysi3 and around a central pulley, i, beneath the same, so that as theslide is drawn across the lay the pulleys i and their shafts h androllers m are caused to turn, a movement in one direction being impartedto said pulleys, shafts, and rollers as the slide is drawn from left toright, and a movement in the opposite direction as the slide is drawnfrom right to left, the pulleys and rollers being so proportioned thatas the slide and shuttle are carried across the lay the surfaces of therollers m and hence of the roller n will move at a rate of speedequivalent to or slightly greater than that of the slide; hence as theweight of the shuttle is borne mainly by these rollers very little, ifany, friction will be exerted upon the warp,an d the passage of theshuttle through the shed will be materially facilitated. The shuttle hasat the ends the usual pivoted nipper-jaws, L L, the tails of which areacted upon by springs L, Fig. 5, which tend to close the jaws, and thereare at the ends of the lay the ordinary yielding cams, M M, which actupon the jaws so as to open the same on the outward passage of theshuttl'ethat is to say, the passage away from the center of the lay butyield as the shuttle passes inward or to ward the center of the lay, soas not to open the jaws and cause the release of the hair.

The operation of the jaws for the purpose of releasing the hair iseffected as the shuttle leaves the warp at each side by cams N N,secured to the bar K. The shuttle passes both of these cams; but it isnecessary that each cam shall act upon one jaw only of the shuttle. Thusthe cam N must act upon the rear jaw, L, of the shuttle as the latter isleaving the warp at the right-hand side of the lay, and the cam N mustact upon the rear jaw, L, of the shuttle as the latter is leaving thewarp at the left-hand side of the lay. If both jaws and both cams are inthe same horizontal plane, mechanism must be employed for throwing thecams into and out of action; and in order to avoid the necessity forthis we arrange the tails of the jaws and the cams for acting thereon indifferent planes. Thus, as will be seen 011 reference to Fig. 3, thetail of the jaw L and cam N are on a higher plane than the tail of thejaw L and cam .L so that each cam will act only upon its proper jaw.

' The devices for controlling the action of the heddle operatingmechanism are shown 'in Figs. 1, 2, 6, 7, and 8. A cam, P, on the shaftD acts upon an arm, P, hung to the frame, and in the outer or forwardend of this arm is a slot, 5, for the reception of a catch, 8, hung tothe lower end of a rod, 8 guided on the frame A, and connected at theupper end to an arm, 8, on a rock-shaft, s", the latter having anotherarm, 8 carrying a fork, s, which embraces the pawl f of thepatterndrumoperating mechanism. Vhen the catch 8 is allowed to hangvertically from the lower end of the rod 8', it overlaps the end of theslot 8 in the arm P; hence on each lift of said arm there would be anoperation of the parts just described, and a lifting of the pawl f clearof the ratchet-wheel f, and hence no movement of the pattern-drum. Thecatch 8, however, has a slot, 8 to which is adapted a finger, t, on arod, t, pendent from a rock-shaft, t, on the frame, so that wheneversaid rod is thrust rearward the catch 3 will be moved into line with theslot 8, and the elevation of the arm P will have no effect upon theheddleoperating mechanism.

To bearings on the rear of the bar 9 of the lay is adapted a shaft, 10,having at each end a finger, w, and furnished also with an arm, 20",bent at the outer end and connected to a guided rod, 10 the lower end ofwhich as the lay swings forward is brought under control of a cam, w",on the frame A of the loom, which has the effect of depressing thefingers w and elevating the arm w, so that the rod t will be in the pathof the same as the lay swings rearward. If a hair has been lifted by theselecting device and caught by the shuttle at either side of the loom,it will, as the shuttle moves across the lay, be drawn 'over the fingerat that end of the lay, and will hold said finger down as the lay swingsback, thus maintain ing the arm in the elevated position, so as to pushback the rod 1 and release the catch s from the control of the arm P;hence there will be the proper operation of the heddle mechanismnecessary to effect a change of shed. If the shuttle fails to catch ahair, however, the fingers w will rise as soon as the rod w is free fromthe control of the cam 10, the arm 10 falling, so as to clear the rod t,thus permitting the catch 8 to engage with the arm P, and throwing thepawl and ratchet of the heddle mechanism out of gear; hence there will.be no change in the shed.

If desired, the arm to may be adapted to act directly upon the catch s,or upon an arm proj ecting therefrom, and in some cases theheddle-operating mechanism may be arranged with reference to the rod 8acting directly upon the pawl f or through the medium of devices otherthan the rock-shaft and arms shown,

In Fig. 8 we have shown the above modifications, the arm 10 beingarranged to strike an arm on the catch 3, and the upper end of the rod8" being bent so as to act directly on the pawl f WVe do not claim,broadly, a rotating-roller support for the shuttle, as suchroller-supportshave been heretofore employed, but have been operated byfrictional contact with the lay, whereas our plan of driving the rollersis more positive and less. liable to interruption during the working ofthe loom; neither do we claim, broadly, the nipping-jaws L L, havingtails in different planes, in combination with cams, one for actuatingone jaw, and the other for actuating the opposite jaw, as this has alsobeen proposed; but in former looms the cams have been located on thefront of the lay-a construction which is inadmissible in our loom, asthe slide F traverses this portion of the lay; hence we secure the camsfor operating the nipping-jaws to the upper bar, K,

where they are out of the way of the slide.

\Ne claim as our invention 1. The combination of the lay, the slide F,guided thereon, and having a pulley, i, and shafts h h, provided withrollers m m. and pulleys i i, with the cord I, passing round saidpulleys and fastenedat its opposite ends to the lay, the shuttle havinga roller, 11, resting on the rollers m, and mechanism for reciprocatingthe slide on the lay, as set forth.

3. The combination of the heddleoperating mechanism, its pattern-drum,and operating pawl therefor with the arm P and its cam, the lay B, theshaft 10, having fingers w and arm with rod 103, the cam w, and devices,substantially as described, under control of the arm w, whereby the armP is caused to act upon or is thrown out of connection with theoperating-pawl of the pattern-drum, as set forth.
